A mysterious and gruesome crime ended the life of 19-year-old Jessica Chambers .

She was found badly burned Saturday night on a rural Mississippi road by first responders after a passerby called 911 .

`` You could n't recognize her because she was unrecognizable , '' her father , Ben Chambers , told CNN affiliate WREG .

As her car continued to blaze , emergency workers struggled to hear Chambers ' final words . She spoke in a hoarse voice , Jay Hale , the assistant district attorney for Panola County said .

Did she identify her killer ?

Hale paused and told CNN that no one was in custody yet , so it 's still not known .

Ben Chambers said doctors told him his daughter was burned over 98 % of her body .

`` They have ripped everything I have , '' her mother , Lisa Chambers , told CNN affiliate WMC .

Jessica Chambers went to go clean out her car and get something to eat before she was burned alive , her mother said ,

Authorities have questioned a few people , but no one has been arrested , Hale said .

They are also trying to get a call record and data from her cell phone , found at the scene near the town of Courtland in northwestern Mississippi .
